**Affirmed position.** Signal Transduction from N-cadherin Increases Bcl-2 presents the following source proposition: Associated with the metastatic progression of epithelial tumors is the dynamic regulation of cadherins. This proposition is pertinent to Kaal's source-bound claim that The collective action problem of rulemaking, the problems of trial-and-error rulemaking, and the problems of regulatory cycles derive largely from the nature of stable and presumptively optimal rules themselves, not from unrelated institutional defects. The proposed response is an extension: the relationship should remain limited to the retrieved source proposition and the mapped Kaal claim unless fuller source review supports a broader conclusion.

**Status.** affirmed  **Published.** 2026-07-31
